Abstract: ABSTRACT OF THE DISCLOSURE The present invention is directed to novel methods and apparatus for conducting chemical and biological reactions.  A reactor is provided that includes a reaction matrix member formed from microporous ceramic. The chemical or biological material is fixed within the pores of the porous matrix, and reaction solution is passed through the porous matrix member at a controlled rate.  Preferably, the matrix member is tubular in shape and comprises a plurality of concentric layers of ceramic material, each layer having a substantially uniform pore size, but the plurality of layers having a progressively decreasing pore size with respect to the preceding layer. Each layer may also have a different thickness than other layers.  Reaction solution is introduced into an axial bore through the ceramic matrix member, and the product solution is collected from the outside of the ceramic matrix member.  Optionally, lumens within one or more adjacent ceramic layers, and or spaces between layers can be provided.

Abstract: CIRCUIT FOR DETECTING KEYPAD CONDITIONS IN A MICROPROCESSOR CONTROLLED TELEPHONE INSTRUMENT               ABSTRACT OF THE DISCLOSURE A technique for evaluating keypad conditions while utilizing only a minimum number of ports in a microprocessor involved in control of a telephone instrument.  Because of the limited number of ports available and necessity to also evaluate conditions of mode selecting strap switches, the utilization of a reduced number of ports is highly desirable in such an enviroment.  Such a reduction becomes an ab-solute necessity particularly in dealing in those enviroments that include random access memories, read only memories, pulse dialers, integrated circuits and liquid crystal displays.  A combination of diode gating, resistive decoupling and time multiplexing techniques are used to match the input/output require-ments to the available ports of a specific micropro-cessor.

Abstract: ABSTRACT          Welding apparatus is disclosed for collecting and disposing of the extraneous work piece particles thrown off during the machining and, in particular, the welding  of the  workups.   The  welding  apparatus comprises a welding chamber for receiving the work piece and for establishing a welding environment about the work piece.  The welding chamber has an opening and an input port for introducing a non-reactive gas into the welding chamber to establish the welding environment within the welding chamber.  An output port is associated with its welding  chamber  for permitting the  escape  of  the non-reactive gas therefrom.  A manifold is disposed about the  output port  for  receiving  and  collecting  the non-reactive gas and the work piece particles suspended therein.  A sealing assembly is associated with the opening for operating in a first mode for sealing the opening to prevent escape of the non-reactive gas except through the output port and the manifold means, and in a second mode to permit escape of the non-reactive gas through the opening.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method of bonding plastic pipes by inserting a plastic pipe into a plastic joint and melt-bonding them together, which is a so-called socket bonding method.  The inner circumferential surface of the socket portion of a plastic joint is tapered so that the socket portion becomes progressively smaller in diameter in a direction away from its end portion, or the outer circumferential surface of the end portion of the plastic pipe is tapered so that the end portion becomes progressively smaller in diameter towards its insertion end.  When the end portion of the plastic pipe is to be heated, the length from its insertion end of the part to be heated is made nearly equal to the final insertion length of the pipe.  When the socket portion of the plastic joint is to be heated, the length from the socket end of the part to be heated is made shorter than the final insertion length of the pipe by a predetermined distance.

Abstract: ABSTRACT OF THE DISCLOSURE   The present invention is a ready-to-use microtube and method for the simple and accurate identification of beta-hemolytic streptococci from inoculated swabs. Non-volatile reagents are selected and affixed to two separate loci within the microtube by means of a stable, water-soluble or -dispersible binder. At the time of patient examination, the patient site (pharynx, etc.) is swabbed and the swab is placed, tip down, in the prepared microtube. Four to six drops of distilled water are added, the swab is rotated and, after a brief incubation period, an agglutination agent is used to verify the presence or absence of a specific streptococcus group antigen by the presence or absence of a visible agglutination. The test is suitable for use in identifying any streptococcus group which bears antigens susceptible to extraction by nitrous acid, including in particular the clinically significant group A, B, C, F, and G beta-hemolytic streptococci.

Abstract: Compsn. comprises a protease resistant single-chain urokinase (I). (I) may be prepd. by (a) providing nucleic acid encoding a protease-resistant amino acid sequence variant of single-chain urokinase, (b) transforming a host cell with the nucleic acid, (c) culturing the transformed host cell until the variant urokinase accumulates in the culture and (d) recovering the variant urokinase from the culture. (I) is produced by combining urokinase with an agent to complex with urokinase or by covalently modifying single-chain urokinase at sites of proteolysis. The target sites include Arg156 to Lys158 and, pref., the site at residues Lys135 to Lys136. Covalent modifications are accomplished by reacting native urokinase with derivatising reagents or by the recombinant synthesis of mutants having site specific substns., insertions or deletions of amino acid residues at target sites. Complexing agents such as antibodies bind to urokinase at the target sites or at flanking sites so that access to the sites by proteases is impeded or prevented.

Abstract: The invention relates to the distribution on a receiving device of fibers carried by a gas current. To improve the distribution, the gas current carrying the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current. The action of the gas layer results in an expansion of the current carrying the fibers. The invention is particularly useful where the fibers are received on a collecting device such as a foraminous conveyor belt, of large width.
